Static IP Address
When the Router is configured to use Static IP Address assignment for the WAN connection, you must manually assign
a global IP Address, Subnet Mask and Gateway IP Address used for the WAN connection. Most users will also need to
configure DNS server IP settings in the
DNS Configuration
window (see below). Follow the instruction below to
configure the Router to use Static IP Address assignment for the WAN connection.
To configure a Static IP Address connection, perform the steps listed below. Some of the settings do not need to be
changed the first time the device is set up, but can be changed later if you choose. See the table below for a description
of all the settings available in this window.

WAN Settings window - Static IP
To configure a Static IP type connection for the WAN, follow these steps:
1.
Choose the
Static IP Address
option from the
WAN Settings
pull-down menu.
2.
Under the
ATM VC Settings
at the top of the window should not be changed unless you have been instructed to
change them. However, if you are instructed to change the
VPI
or
VCI
values, type in the values assigned for

your account. Leave the
PVC
and
Virtual Circuit
setting at the default (
Pcv0
and
Enabled
) values for now. This
can be used later if you are configuring multiple virtual circuits for your ADSL service. For more information on
ATM VC Settings, see the table on page 41 below.
3.
Under the
Static IP
heading, choose the
Connection Type
from the pull-down menu. This defines both the
connection type and encapsulation method used for your ADSL service. The available options are
Bridged IP
LLC
,
Bridged IP VC-Mux
,
Routed IP LLC
,
Routed IP VC-Mux
or
IPoA
. If have not been provided specific
information for the Connection Type setting, leave the default setting.
4.
Change the
IP Address
,
Subnet Mask
,
Gateway Address
and (if available)
Secondary DNS
Server IP address
as instructed by your ISP. These are the global IP settings for the WAN interface. This is the “visible” IP address
of your account. Your ISP should have provided these IP settings to you.
5.
Leave the
MTU
value at the default setting (default =
1400
) unless you have specific reasons to change this (see
table below).
6.
NAT
should remain
Enabled
. If you disable NAT, you will not be able to use more than one computer for
Internet connections. NAT is enabled and disabled system-wide, therefore if you are using multiple virtual
connections, NAT will be disabled on all connections.
7.
The
Firewall
should remain enabled for most users. If you choose to disable this you will not be able to use the
features configured in the
Firewall Configuration
and
Filters
window located in the
Advanced
directory. See
the next chapter for more details on these windows.
8.
Most users will not need to change
ATM
settings. If this is the first time you are setting up the ADSL connection
it is recommended that you leave the
Service Category
settings at the default values until you have established
the connection. See the table on page 40 for a description of the parameters available for ATM traffic shaping.
9.
When you are satisfied that all the WAN settings are configured correctly, click on the
Apply
button.
10.
The new settings must be saved and the Router must be restarted for the settings to go into effect. To save and
reboot the Router, click on the
Tools
directory tab and then click the
System
button. In the
System Settings
window, click the
Save and
Reboot
button under Save Settings and Reboot the System.
11.
Click
OK
when the following “Save and restart?” dialog box opens.
12.
The Router will save the new settings and restart. Upon restarting the Router will automatically establish the
WAN connection.

Static IP Parameters
Description
Connection Type
This specifies the connection type and the encapsulation method used for
your Static IP Address connection. The options available are
Bridged IP LLC
,
Bridged IP VC-Mux
,
Routed IP LLC
,
Routed IP VC-Mux
or
IPoA
.
IP Address
This is the permanent global IP address for your account. This is the
address that is visible outside your private network. Get this from your ISP.
Subnet Mask
This is the Subnet mask for the WAN interface. Get this from your ISP.
Gateway Address
This is the IP address of your ISP’s Gateway router. It provides the
connection to the Router for IP routed traffic that is outside your ISP’s
network. That is, this will be the primary connection from the Router to
most of the Internet. Get this IP address from your ISP.
Primary DNS Address
This is the IP address of the first choice for Domain Name Service (DNS)
used to match the named URL web address used by most browsers with
the actual global IP address used for a web server. Usually this will be a
server owned by the ISP. Get this IP address from your ISP.
Secondary DNS Address
This is the second choice for a DNS server. Get this IP address from your
ISP.
MTU
The Maximum Transmission Unit size may be changed if you want to
optimize efficiency for uploading data through the WAN interface. The
default setting (
1400
bytes) should be suitable for most users. Some user
may want to adjust the setting to optimize performance for wireless traffic
or when low latency is desired (such as with Internet gaming). It is highly
recommended that the user research how adjusting the MTU may affect
network traffic for better or worse.
NAT
Network Address Translation may be enabled or disabled with the pull-
down menu. Keep in mind that disabling NAT allows on a single computer
to be used for Internet access through the Router. NAT is enabled and
disabled for the Router on all connections (i.e. Pvc0 – Pvc7) if your Router
is set up for multiple virtual connections.
Firewall
Use this to universally enable or disable the Firewall and Filter features
available in the Router. If you disable this you will not be able to configure
settings in the
Firewall Configuration
window or the
Filters
window in
the
Advanced
directory.

ATM Traffic Shaping
The ATM settings in the WAN Settings windows for the different connection types can be used to adjust QoS
parameters for ADSL clients. This may not be available to all ADSL accounts.
ATM Settings for WAN connection
Additional ATM settings for PPPoE or PPPoA connections:
ATM Parameters
Description
Service Category
The ATM settings allow the user to adjust ATM Quality of Service (QoS) or
traffic parameters to suit specific traffic requirements. For applications or
circumstances where packet loss or packet delay is a concern, ATM QoS can
be adjusted to minimize problems. For most accounts, it will not be
necessary to change these settings. Altering QoS settings can adversely
affect performance of some commonly used Internet applications.
If you plan to change QoS or traffic parameters, contact your ISP or
network services provider for information on what types of adjustment are
available or possible for your account. Your ISP may not support the class
of service you want to use.
To adjust ATM QoS parameters, select one of the Service Categories listed
here and type in the PCR value in the entry field below. For the VBR service
category, an additional parameter (SCR) must also be defined.
UBR
– Unspecified Bit Rate, this is the default category used for general-
purpose Internet traffic where normal levels of packet loss and delay are
acceptable. For some applications or for multiple connection accounts, it
may be desirable to specify the PCR.
CBR
– Constant Bit Rate, usually used in circumstances where very low
packet loss and very low Cell Delay Variable (CDV) are desirable.
VBR
– Variable Bit Rate, usually used when network traffic is characterized
by bursts of packets at variable intervals, and some moderate packet loss
and delay is acceptable. This category is typically used for audio and video
applications such as teleconferencing. The network must support QoS Class
2 to use VBR.
PCR
Peak Cell Rate – The PCR is inversely related to the time interval between
ATM cells. It is specified for all three service categories (UBR, CBR and
VBR) in Kbps.
